Application filed June 5, 1903.

Renewed May 23, 1905. Serial No. 261,852.

To all 1071/0171 it may eon/oer.-

l'le it known that I, Il lnms L. Ei'miorr, a citizen of the United States, resid i ng at New York, in the county of New York and dtate oi New lii'ork, have in rented certain new and usell 11 improvements in Multiple .lClectric-Lamp llolders, of which the following is a specification.

This invention relates to multiple sockets or holders for incandescent electric lamps.

'lhe object of the invention is to produce a socket or holder of few parts and preferably having a non-conducting body; also, to make the conducting-wires readily accessible and to so connect the lamps with their conductors by the mere armlication ot' the lamp to its proper position; also, to improve the details. of coir struction of lamp-holders of this character.

liigure 1 is a vertical section of a holder embodying the general principles of my invention. .l ig. 2 is a plan or elevation o'l the body part. 1* 1g. 3 is a reverse view from liig. 2,

showing contact-rings.

The body A is of porcelain or other non conductor of electricity and is 'n'elerably approxii'mltely in form a segment of a sphere. .lfn this body there are as many sockets ll as may be convenient or desirable, each socket having therein, embedded in the nonconducting material and fully supported thereby, as shown, a screw-tln-eaded shell 0, of brass or other metal. The body ll. is hollow, and around the interior opening there is a flared ring E, oi metal. A screw l? passes through the body from the center of said socket and enters the ring it. A binding-post Gr connects a conducting-wire H to the ring l Thus all the screws l! are insulated by the body oi the holder, but are in position to become comluctors or contact-pieces for the lamps as soon as the lamps are screwed home in their sockets. The body it has a shoulder l surrounding its central opening, and a metallic ring K rests on this shoulder, being held thereto by a screw L, which passes through the body in a generally longitudinal (lllGGtlOll. This screw l1 also serves as a binding-post for one of the condnoting-wires lVl. it will be seen that both the bi mling-posts are accessible from the open end of the holder. Each metallic shell 0 has a tongue U, which passes through an opening in the body and rests on ring KI. Thus the return or grmmd circuit. with all the lamps which may be applied to the holder, is made through the respective shells, the ring 1C, and. the bimjling-post L.

For convenience in construction and assemblage the central (.n iening in the body A is oi a generally frusto-conical form when viewed. from either end. A metallic or other strong base N is attached to the porcelain body by screws l or in other convenient manner. This base has a central spider It, into which a screw 1") is tapped. Screw 5%? passes through a segmental cap '1, which cap covers the open end of the holder. The opening in the body being conical, this cap comes readily to place to close the opening at the [)lOjGCllll'lg' end of the holder, making a neat linish, easily detachable to permit a loose to the binding-posts and con ducting-wires. 'lhc base-piece N is preferably provided with an internal screw-thread T, by which the holder can be attached to any threaded tube or projection.

This holder is of few parts, and the body being a non-conductor there is little danger oi. the lamps being short'circuited at any point.

Each lamp can be removed and replaced without interfering with any other.

While three sockets have been illustrated in the holder shown, it is evident that any convenient number of lamps may be attached to a single holder.

\ l hat l claim 1. in a multiple holder as described, anonconducting body having a central passage, a shoulder surroumling said passage and a melallic ring thereon, a metallic coi'mectiou from said ring to each socket, and electrical connection through the central passage to the front of the body and back through the body to said ring.

2. A. n'nidti ile holder for electric lamps, consisting of a body ol non-comlucting material substantially in form ol' the l rustum of a hollow sphere and provided with a plurality of sockets, each socket having ascrew-threaded metallic shell embedded therein, return In testimony whereof Iaflix my signature in connections from all these shells to a single presence of two Witnesses. a:
